running the risk of alienating completely its traditional base
Have you ever voted for AKEL?
I voted for AKEL in last parliamentary elections, and a part of my family "traditionally" votes for this party. I, and my family would be alienated if AKEL supported "yes" for the Annan plan. According to polls the vast majority of AKEL supporters rejected the Annan plan before AKEL finally decided to reject it.
Therefore AKEL would alienate a far bigger part of its voters if it had supported the "yes" vote, and it will loose half of its power if it makes any alliance with DISY (this happened before, and AKEL became 3rd party in power during that time).
They've long broken loose from their hardliner support (the coup de grace was the Anastasiadis Vs. Prodromou-Erotokritou thing)
So what you call "hardliners" are Eroticritou and Prodromou, who were some of the younger party leaders? And you call them in this way because they supported "no"???? So according to you the 76% of GCs are hardliners because they didn't accept the unfair partition plan?
It would be better if Anastasiades instead of throwing out some of the younger party leaders who could challenge him for the presidency of the party, was throwing out all those EOKA-B members and the other traitors who for once again are doing the dirty job for the Americans.
